CompTIA A+ 220-602 Examination Objectives

Introduction
In order to receive CompTIA A+ certification a candidate must pass two exams. The first exam is CompTIA A+ Essentials. Objectives for the CompTIA A+ Essentials Examination are available for public review at www.comptia.org. The CompTIA A+ 220-602 exam is targeted for individuals who work or intend to work in a mobile or corporate technical environment with a high level of face-to-face client interaction. Job titles in some organizations which are descriptive of the role of this individual may be: Enterprise technician, IT administrator, field service technician, PC technician, etc. Ideally, the CompTIA A+ 220-602 candidate has already passed the CompTIA A+ Essentials examination. Individuals in some non-technical roles such as student, sales personnel or small business office managers may also find the validation of skills associated with the CompTIA A+ credential to be valuable. CompTIA recently convened a core of CompTIA A+ subject matter experts representing a diverse group of employers, educators and IT professionals which resulted in the revised CompTIA A+ examinations objectives. The skills and knowledge measured by these objectives were validated through a survey of more then 5,000 CompTIA A+ certified professionals and employers. The results of the survey were used in weighting the domains and ensuring that the weighting is representative of the relative importance of that content to the job requirements of an entry-level IT professional. This examination blueprint includes domain weighting, test objectives, and example content. Example topics and concepts are included to clarify the test objectives and should not be construed as a comprehensive listing of all the content of this examination. The table below lists the domains measured by this examination and the extent to which they are represented. CompTIA A+ 220-602 (2007 Edition) exams are based on these objectives.

Domain 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 Personal Computer Components Laptop and Portable Devices Operating Systems Printers and Scanners Networks Security Safety and Environmental Issues Communication and Professionalism

CompTIA is constantly reviewing the content of our exams and updating test questions to be sure our exams are current and the security of the questions is protected. When necessary, we will publish updated exams based on existing exam objectives. Please know that all related exam preparation materials will still be valid.
